Galen i tested what you said about the little trick of making the lv the
same size and it works like a charm, have u used this trick many times? in
what situation?.
cazerez i dont what to share vgora i whant a copy in both machines, the only
thing is that i have the chance to share the disk, but thnkX for the idea, i
didnt think about it
